6
The nurse is caring for a patient who has dumping syndrome from high carbohydrate foods being administered over a period of less than 20 minutes. What is a nursing measure to prevent or minimize the dumping syndrome?
Administer the feeding with the patient in semi-fowler's position to decrease transit time influenced by gravity.
The nurse is inserting a nasogastric tube for a patient with pancreatitis. What intervention can the nurse provide to allow facilitation of the tube insertion?
Allow the patient to sip water as the tube is being inserted.
The physician ordered a nasoenteric feeding tube with a tungsten-weighted tip. The nurse knows to obtain what kind of tube?

Triple-lumen, rubber nasogastric tube (2 lumens are used to inflate the gastric & esophageal balloons)
Sengstaken-Blakemore tube
The nurse is inserting a sump tube in a patient with Crohn's disease who is suspected of having a bowel obstruction. What does the nurse understand is the benefit of the gastric (Salem) sump tube in comparison to some of the other tubes?

The nurse is inserting a nasoenteric tube for a patient with a paralytic ileus. How long does the nurse anticipate the tube will be required? Select all that apply.
Until bowel sound is present Until flatus is passed Until peristalsis is resumed
The nurse checks residual content before each intermittent tube feeding. When should the patient be reassessed?
When the residual is greater than 200 mL
The nurse is caring for a comatose patient & administering gastrostomy feedings. What does the nurse understand is the reason that gastrostomy feedings are preferred to nasogastric feedings in the comatose patient?
Gastroesophageal sphincter is intact, lessening the possibility of regurgitation
A nurse prepares a patient for insertion of a nasoenteric tube. What position should the nurse place the patient in?
In high fowler's position
The nurse is managing a gastric (Salem) sump tube for a patient who has an intestinal obstruction & will be going to surgery. What interventions should the nurse perform to make sure the tube is functioning properly?

Name three common causes of constipation for a patient who is receiving enteral feedings.
Possible causes for constipation include: concomitant use of opiods; administration of fiber free tube feeding formulas; & inadequate water intake (tube feedings typically do not meet total fluid needs, so additional water must be administered).
